Prospects For Rnai Therapy Of Covid-19, Hasan Uludağ, Kylie Parent, Hamidreza Montazeri Aliabadi, Azita Haddadi

Pharmacy Faculty Articles and Research

COVID-19 caused by the SARS-CoV-2 virus is a fast emerging disease with deadly consequences. The pulmonary system and lungs in particular are most prone to damage caused by the SARS-CoV-2 infection, which leaves a destructive footprint in the lung tissue, making it incapable of conducting its respiratory functions and resulting in severe acute respiratory disease and loss of life. There were no drug treatments or vaccines approved for SARS-CoV-2 at the onset of pandemic, necessitating an urgent need to develop effective therapeutics. To this end, the innate RNA interference (RNAi) mechanism can be employed to develop front line therapies against …

Outlaw Operators: Prevention Failures And The Resurgence Of Black Lung In Central Appalachia, Aysha Bodenhamer

Carsey Publications

In this brief, author Aysha Bodenhamer describes how prevention failures in the coal mining industry have resulted in the resurgence of black lung disease. Caused by the chronic inhalation of coal and silica dust, black lung is progressive, incurable, life-altering, and fatal. Despite it being a preventable disease, black lung is resurgent among coal miners in Kentucky, Virginia, and West Virginia. Fieldwork including in-depth interviews with miners, clinic workers, black lung attorneys, government employees, and lay advocates, and a case-study analysis of two black lung clinics in southwest Virginia inform this analysis. These data reveal that coal operators routinely evade …

The University of Louisville Journal of Respiratory Infections

Introduction: The early automatic diagnosis of the novel coronavirus (COVID-19) disease could be very helpful to reduce its spread around the world. In this study, we revisit the identification of COVID-19 from chest X-ray images using deep learning.

Methods: We collected a relatively large COVID-19 dataset—compared with previous studies—containing 309 real COVID-19 chest X-ray images. We also prepared 2,000 chest X-ray images of pneumonia cases and 1,000 images of healthy controls. Deep transfer learning was used to detect abnormalities in our image dataset. We fine-tuned three, pre-trained convolutional neural network (CNN) models on a training dataset: DenseNet 121, NASNetLarge, and …

Exogenous Lipoid Pneumonia Complicated By Mineral Oil Asperation In A Patient With Chronic Constipation: A Case Report And Review, Hafiz Muhammad Jeelani, Muhammad Mubbashir Sheikh, Belaal Sheikh, Hafiz Mahboob, Anchit Bharat

School of Medicine Faculty Research

Exogenous lipoid pneumonia is a rare and frequently misdiagnosed lung disease. It occurs as an inflammatory reaction secondary to either aspiration or inhalation of lipids. Our patient had a history significant for recurrent pneumonia and the use of mineral oil for chronic constipation. A chest computed tomography showed multifocal consolidative opacities with areas of low attenuation, highly suspicious of exogenous lipid pneumonia. The diagnosis was confirmed with combined bronchoalveolar lavage and transbronchial lung biopsy that showed lipid-laden macrophages consistent with exogenous lipoid pneumonia. After thorough medication review, apart from mineral oil, no other contributing factors were found. A diagnosis of …

HCA Healthcare Journal of Medicine

The recent pandemic of SARS-CoV-2, which causes novel coronavirus disease 2019 (Covid-19), has had devastating impact on a global and national scale. In order to overcome this outbreak it is imperative we find treatments that are safe and effective. To date, no definitive treatment is available that can curtail the spread of this viral syndrome. Convalescent plasma (CP) is one such option that has repeatedly served as an important tool in treatment of various bacterial and viral infections, especially in the setting of no specific antimicrobial or vaccination against an infectious disease. Herein, we review the history of CP, prior …

Chronic Thromboembolic Pulmonary Hypertension, Alyssa Curry

Nursing Student Class Projects (Formerly MSN)

Chronic pulmonary hypertension (CTEPH) is a rare and underdiagnosed complication of unresolved acute pulmonary embolism (PE). A chronic fibrotic thrombus replaces the unresolved emboli in the pulmonary vascular bed causing pre-capillary pulmonary hypertension (Mahmud et al., 2018). Symptoms rang from mild nonspecific such as exercise intolerance and dyspnea. As the disease progresses, symptoms present similarly to right ventricular heart failure (Gopalan et al., 2016). Although the pathophysiology and etiology of CTEPH is still not fully understood, risk factors include increased size of the PE, right ventricular strain, chronic inflammation, and defects in fibrinolysis among others (Fernandes et al., 2016). Treatment …

Phosphodiesterase Isoforms And Camp Compartments In The Development Of New Therapies For Obstructive Pulmonary Diseases, Martina Schmidt, Isabella Cattani-Cavalieri, Francisco J. Nuñez, Rennolds S. Ostrom

Pharmacy Faculty Articles and Research

The second messenger molecule 3′5′-cyclic adenosine monophosphate (cAMP) imparts several beneficial effects in lung diseases such as asthma, chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). While cAMP is bronchodilatory in asthma and COPD, it also displays anti-fibrotic properties that limit fibrosis. Phosphodiesterases (PDEs) metabolize cAMP and thus regulate cAMP signaling. While some existing therapies inhibit PDEs, there are only broad family specific inhibitors. The understanding of cAMP signaling compartments, some centered around lipid rafts/caveolae, has led to interest in defining how specific PDE isoforms maintain these signaling microdomains. The possible altered expression of PDEs, and thus abnormal …

The Covid-19 Pandemic And The Power Of Numbers, Jessica Ancker

Numeracy

The COVID-19 pandemic has produced a deluge of news coverage of quantitative concepts. In this viewpoint, we provide examples of effective and poor quantitative communication by the professional news media as well as social media communicators. Effective examples include a number of online animations and engaging interactive simulations. Examples of poor quantitative communication include the widespread reporting of raw numbers rather than rates, failing to address uncertainty, not providing sufficient context for numbers, and not discussing the implications of false negative and false positive diagnostic test results. Educators can draw from this body of news to develop compelling quantitative literacy …

Iatrogenic Pneumothorax With Subsequent Subcutaneous Emphysema, George Michael, Eric Yuschak, My Myers

West Florida Division GME Research Day 2020

Lung cancer is the leading cause of cancer-related death in the United States, accounting for 13% of all new cancer diagnoses and 24% of all cancer deaths.1 Transthoracic CT-guided biopsy (CTGB) is commonly used as a diagnostic tool for lung cancer, with high diagnostic accuracy, sensitivity, and specificity. 2 This procedure, however, is not without its risks which include pulmonary hemorrhage and iatrogenic pneumothorax (IPNX). Emergent chest tube placement is standard care of treatment for massive or symptomatic IPNX, commonly with the use of smaller caliber chest tubes. 2 There is, however, a growing discussion over use of larger caliber …

Acute Hypoxic Respiratory Failure Due To Organizing Pneumonia With Lipoid/Cholesterol Component Caused By Thc Vaping With E-Cigarette, Jinal K. Patel, Kiran Tirumalasetty, Jessica Khabra, Imran Khan, Johnathan Frunzi

West Florida Division GME Research Day 2020

Vaping has been the new and deemed “safer” way to inhale addictive chemicals such as nicotine and tetrahydrocannabinol (THC), but it does not encompass the detrimental effects of other ingredients in these vaping cartridges that can cause lung injury[1,2]. Similar studies with dabbing (heating THC wax concentrate at high temperatures with butane) showcase rapidly progressing lung injury with massive consolidation and lasting effects on lung parenchyma over a period of time [3]. This case report aims to educate people, especially the younger generation, of the dangers of newer ways of combustible alternatives that have been marketed as a “safer” way …

Modulator Therapy For Cystic Fibrosis: An Exploration Of Current Research, Jessalyn Rombocos

Senior Honors Theses

Developing a drug therapy that addresses the root cause of cystic fibrosis (CF) by increasing CFTR protein levels has long been a research challenge. After genetic therapy failed because a suitable delivery system could not be found, researchers began searching for small organic molecules that could act as chaperones for CFTR. These molecules, known as modulators, allowed CFTR to be assembled correctly and function similarly to wild type CFTR. Since 2012, four modulator drugs have been developed, tested, and approved by the FDA. In October 2019, Trikafta was approved as the first triple-combination modulator drug and has completely revolutionized CF …

Global Burden Of Respiratory Infections Associated With Seasonal Influenza In Children Under 5 Years In 2018: A Systematic Review And Modelling Study, Xin Wang, You Li, Katherine L. O'Brien, Qalab Abbas, Syed Asad Ali, Respiratory Virus Global Epidemiology Network, Mohammad Tahir Yousafzai, Zulfiqar Ahmed Bhutta, Sajid Bashir Soofi, Anita K. M. Zaidi

Department of Paediatrics and Child Health

Background: Seasonal influenza virus is a common cause of acute lower respiratory infection (ALRI) in young children. In 2008, we estimated that 20 million influenza-virus-associated ALRI and 1 million influenza-virus-associated severe ALRI occurred in children under 5 years globally. Despite this substantial burden, only a few low-income and middle-income countries have adopted routine influenza vaccination policies for children and, where present, these have achieved only low or unknown levels of vaccine uptake. Moreover, the influenza burden might have changed due to the emergence and circulation of influenza A/H1N1pdm09. We aimed to incorporate new data to update estimates of the global …

Us Guided Management Of Undifferentiated Dyspneic Patient In The Ed, Kaleigh Miller

Longitudinal Scholar's Project

Intro: Undifferentiated dyspnea can be a complicated presentation muddled by patient comorbidities and similar symptomology shared among etiologies. Some studies have shown increased mortality and length of stay in the hospital when incorrectly initially diagnosed in the ED. US has been shown more effective at differentiating these causes and improves diagnostic accuracy. This study will implement US exam upon initial exam of patient and chart time to diagnosis/treatment, length of stay in ED, length of stay in hospital admissions versus discharge rates, and 30 day mortality. ADHF and COPD/asthma patient differentiation will be the focus.

Methods: Prospective cohort study of …

Hemodynamic And Clinical Effects Of Selexipag In Children With Pulmonary Hypertension, Abraham Rothman, Gabriel Cruz, William N. Evans, Humberto Restrepo

School of Medicine Faculty Research

Selexipag is an oral prostacyclin receptor agonist; it was recently approved for use in adults with pulmonary arterial hypertension. The safety and efficacy of selexipag has not yet been determined in the pediatric population. We describe short-term hemodynamic and clinical data with selexipag therapy in four pediatric patients with pulmonary hypertension. We reviewed clinical, echocardiographic, and hemodynamic data. One patient was transitioned from subcutaneous treprostinil to selexipag, and in three patients, selexipag was added as a third agent. Drug dosing was attained empirically based on patient body size. A follow-up catheterization was performed 12–18 months after initiation of selexipag therapy. …
